Is There A Difference Between Heat And Temperature?

 

Heat (measured in joules) is the amount of thermal energy (molecular movement) something has and it can vary depending on the mass of the object; if the object has a large mass, its thermal energy will also, be large as it has a lot of molecules, while a smaller object will have less thermal energy as it has fewer molecules. But temperature is a measure of the relative thermal energy of something; it’s the degree of hotness or coldness, measuring the average kinetic energy in the molecules of an object.

Temperature is not dependent on the mass of an object, so objects of different sizes could have the same temperature, but different heats. So, a mug of tea may have the same temperature as a bath of hot water, but as the bath has more water, it takes more energy to get its molecules to that temperature, and therefore it has more heat.
